Rice drying and screening device

Abstract

The invention provides a rice drying and screening device. The rice drying and screening device comprises a lifting bin, a movable bottom plate is arranged on the bottom of the lifting bin, a liftingmechanism is further arranged in the lifting bin, a lifting bin outlet is formed in the top of the lifting bin, and the lifting bin outlet is matched with a material inlet of a drying and screening bin. The drying and screening device is internally provided with a first screening blower and a second screening blower in sequence, and a division slope matched with the second screening blower is arranged in the middle in the drying and screening bin. A drying inlet and a screening pipeline are arranged on the two sides of the division slopes respectively, a vibrating drying plate is arranged below the drying inlet, and a drying blower is further cooperatively arranged on the left side of the vibrating drying plate. A backflow pipeline and a finished product pipeline are arranged on the bottomof the drying and screening bin, the screening pipeline is communicated with a dust pipeline and a crushed leaf pipeline, and the dust pipeline is communicated with a dirt collection pond. Through the movable bottom plate, rice is more sufficiently lifted; through the screening blower, dust and crushed leaves are effectively separated from the rice; due to the vibrating drying plate, the rice more smoothly falls down and is more uniformly heated; through the backflow pipeline, the rice is circularly dried and screened, the operation quality is higher, and small stones can be effectively removed; due to the dirt collection pond, dust can be effectively precipitated, and pollution to air is reduced.

Description

technical field [0001] The invention belongs to the technical field of grain production equipment, and more specifically relates to a rice drying and screening device. Background technique [0002] Rice drying is a very important process in rice production. If rice is not dried, it is easy to mold and cause a lot of economic losses. Generally, rice drying only adopts a drying method, and the process of rice drying In the same drying area, a large amount of rice is piled up, heated and dried unevenly, and the rice inside cannot be dried, so the drying effect and efficiency are not high. The leaves are broken and mixed into the rice, making the impurity removal of the rice more troublesome, and in the aforementioned processing process, the rice will inevitably be mixed with all small stones, if not removed, it will affect the quality of the rice processed from the rice. At the same time, during the drying process of rice, the dust adhering to the rice will be detached from th...

[0002] Rice drying is a very important process in rice production. If rice is not dried, it is easy to mold and cause a lot of economic losses. Generally, rice drying only adopts a drying method, and the process of rice drying In the same drying area, a large amount of rice is piled up, heated and dried unevenly, and the rice inside cannot be dried, so the drying effect and efficiency are not high. The leaves are broken and mixed into the rice, making the impurity removal of the rice more troublesome, and in the aforementioned processing process, the rice will inevitably be mixed with all small stones, if not removed, it will affect the quality of the rice processed from the rice. At the same time, during the drying process of rice, the dust adhering to the rice will be detached from the surface of the rice due to drying and dehydration. The existing drying process does not deal with the dust, which will cause the dust to enter the air and cause damage to the air. A certain degree of pollution, at the same time, when the workers pack the rice, the dust in the rice will cause damage to the workers' bodies
